this is very nice! i wonder why i am the first after 3 days to write something :/

just what i need it, i will give it a try!

very smooth and customizable kernel for lineageOS oreo based custom ROMs.

Very Nice kernel. A lot of customizations!
Thanks and keep the great work! ?

Hi Palaych,
Thanks for this kernel!
Any plan to make it available for Xperia Z (Yuga) as well?

Can someone please tell me what the highest clock rate is with this
kernel of CPU and GPU?

1728Mhz CPU & 487 Mhz GPU is the limit.

Thanks for the information.
I have the kernel installed. I would like to increase the limit of GPU and CPU.
Want to play games with the tablet.
I can test it at my own risk, then we participate
all of them?

I think for the developer it is a "5 minute project" to increase the limits.
Then each user can decide for himself which limit he uses.

Use app like Kernel Adiutor to set clocks whatever you want withing specified limits.
P.S Though with overclock you'll get only monstrous battery disharge, but no suffucient performance boost. This 6 year old tablet is not for gaming....

Hello Palaych,
Thanks again for this kernel that makes my xperia tablet z running smooth and fast (10% to 20% faster without compromising battery capacity).
I would like to install this kernel in my xperia z (smartphone) but I don't really know what to modify to make it compatible. It is the same hardware. Only differences are a bigger screen, a bigger battery capacity, IR remote and no vibrator for xperia tablet z. Other components are strictly the same (CPU, GPU, RAM, ...).
Can you please help me by compiling MiPa kernel to make it compatible with my xperia z (yuga)?
If you're out of time to do so, could you please tell me what modifications to do? (If you have any documentation on how to build a kernel for xperia z, I am also interested in).
Thanks.

Android 5.1.1 to this 8.1 Installation Process
Hi,
I am really new and do not know how to install custom ROM to my Tablet Z SGP311. Is there any instruction how step by step process i can install the ROM?
Thanks

can you pull request and see if lineage os maintainer will merge some of these patches into the main kernel? it's a bit pain in the butt to check the topic for update and flash it everytime lineage os gets an update

You can try, but some changes just can be merged in LOS, due to their policy.

quick noob question (never flashed a custom kernel before):
I'm currently running the unofficial lineageOS 16 ROM. If I now flash this kernel here, and then later onflash an update of the entire ROM: is it correct to assuem that I would then have to flash the kernel again after the ROM is updated?

Nice. The addition of sigspoofing and substratum service would make plain LOS usable for me. Straight LOS and themes were always iffy.

ZTE Axon 7 A2017U, /e/ v0.1 ROM, microG (NoGapps), Multiboot, XDA Legacy

As nobody really posted here, I just wanted to say that this is working really well.
I had huge gps problems with the last 15.1 unofficial, but it works perfectly in this one and it has some very nice additions as well and is 100% stable for me even with xposed and magisk.
 @admicos Thank you very much and I really hope that, if you have the time, you continue making these.

New build being uploaded right now, no changes other than a LOS repo sync.
The last couple test builds I made were somewhat iffy, but this one seems pretty well. (The recolored boot animation didn't make it in for some reason, but the rest are fine)

Everytime when i reboot the system to os or recovery,the recovery looks replaced and i cant mount data.
Not sure what caused it,i just flashed this on my non treble axon 7

I'm not sure why that's happening either. Can you replicate this on official LOS? If you can, I'd suggest you try asking on their thread, they might know more.

Good ROM for a while, why not update it? Is there a new kernel upgrade for the top post?

What version of Xposed are you using? I've always wanted to try this ROM, but thought there wasn't an official Xposed yet. The others I knew at the time were reportedly shady.

Sorry for the long wait (kinda forgot about this existing :/), and sorry for the bad news;
As I am planning to switch to another phone, I cannot continue making this anymore.
I might continue this as a GSI or something, but I really don't know if that will happen, as Android source is a big mess that I don't think I, and my (reasonably fast) CPU are prepared to handle. (Any pointers to dealing with this are greatly appreciated)
It was a fun two years lurking around.
(ps: The source link is completely borked (and all my sources are gone). I probably should stop trying to be fancy and use a public Git server like a normal person the next time)

If your build env is on Docker, I can easily stage a build server for you. It won't be fast, but you can leave it running all night long if you need, and free up your computer.
Also, if you're not using Docker, I can help you set it up, so anyone else can easily build by themselves if they choose to do so.

Can I upgrade the kernel?

Which is most Stable and Secure ROM ?

Hi Guys,
I am currently on official ROM on my Redmi 4X. I want to install custom ROM. I want stability and security
Could someone please suggest the best ROM I should opt for ?

Android 9 based ROMs are more stable than Android 10 but that doesn't meant Android 10 ROMs are not much stable but Android 9 may not have latest security patch. it depends upon your need.
I would suggest you for Havoc OS both based on Android 9 and Android 10.
Just last month Redmi 4X got 4.9 kernel and many Android 10 ROMs started supporting it which is great. in my opinion you should give it a try on latest Havoc OS.

If you want a custom roms for a daily use then Lineage os 16 is the answer. Yes Los dosnt have any "awesome" extra feature but it is very stable and secure. Another good rom for daily use is Pixel Experience.
The two rom I mention may not offer crazy customization, awesome "extra features" or the most up to date kernel (4.9) but for daily usage they are the best imo.
I use Los 16 with no root (22 april build), its clean, light and quick. Most importantly I'm lucky enough to pass the safetynet with it so I can use my device for banking, pokemon go, netlflix, snapchat and many others.
Edit:
FYI if you want to use a custom rom you must prepare yourself to not be able to use banking app. Even if you dont root your device you may not be able to pass the safetynet on a custom rom. Safetynet is what google use to check wheter your device is "safe" or not. Of course you can find a some workaround to "bypass" the safetynet but I wouldn't recommend you to do it because it may pose a security concern.

Really appreciate your suggestion.
I also narrowed down to Linage OS 16 and pixel experience ROM. I have some follow up question:-
1- You mean other custom ROMs may not be able to pass the safety net. But linage OS 16 able to pass safety net, right?
2- I saw official page but not thread on XDA for official linage OS 16? You directly refereed to official page?
3- Have you tried latest (10th June) build of Linage 10 OS?
3- I want Android pie based Pixel experience ROM which I suppose is more stable then Android 10 based. But on official page it have only android 10 based download link. Could you pls share the download link for android pie based ROM ?

1. No, most rom "should" be able to pass the safetynet if you don't root it. But.. it doesnt mean 100% you can pass. Even if you use the same rom as me it doesn't mean you'll pass. In the end it all boils down to "how and what u use" to flash the rom and luck. Im speaking from personal experience. Not long ago in another device, I changed to a custom rom and I cant pass the safetynet even tho I dont root it.
Fyi I just changed to Pixel Experience plus in my redmi 4x and I'm still able to pass the safetynet. It's luck really.

Sorry I didnt see question 3 n 4...
3. Yes I tried the 10th june build of Los 16 before switching to pe plus (android 10). The 10th june build as far as I'm aware of is almost the same with the 22th april build. It just have the newest security update and under the hood improvements.
I have 2/16 redmi 4x with goodix fingerprints. I dont have any fingerprints issue with the newest official pixel experience plus. I have tried other android 10 custom roms briefly and I dont see any issue with fingerprints. Ironically when I installed Los 16 (22 april build) my finger print dont work, I restored my persist backup to fix it. No matter what dont forget to back up everything.
I dont have official pixel experience pie. But I do have an unofficial pixel experience plus pie(android 9), I have not tried this rom yet but If you want I can share it.

There were issue with Goodix fingerprint sensor but as far as i remember it's been solved. my device has FPC fingerprint sensor so had no such issues.
I haven't seen anyone complaining about fingerprint sensor in recent few weeks so i can say it is working fine.
If there is any ROM specific issue with fingerprint that someone talking then i don't know because currently i am on Havoc 2.9 and since last week i haven't checked respected ROMs threads and its discussions as i was busy.
4.9 Kernel been added to Redmi 4X which is greatest thing ever could have happened with device, actually i wasn't expecting it as Redmi 4X is almost a 3 years old device.
4.9 kernel improves overall performance of device and basically you can expect even longer support for Redmi 4X in the future.

After trying PE for a few days here is what I have to say about it
Pros:
- as expected, it has more features than Los
- google assistant is quite usable
- surprisingly I don't see much difference in battery life compared to lineage os.
- overall it's pretty good and stable ROM
Cons:
- now I'm using havoc os because it can't read my third Sim card(it can read my other two just fine)
- Small font, the biggest font size it has is still smaller than the default font size in LOS. This issue affects me pretty heavily because I do hours of reading in my phone. In Los I can read for whole days without problems. But in PE after only reading for few hours I'm already at my limit.
Summary: PE is pretty good. But unfortunately it can't read one of my sim.
Additional info:
Using Lineage is will encrypt your phone, if you have decrypted your device, flashing Los will automatically encrypt it. Some twrp or other custom recovery can't read encrypted phone.
I use this lovely unofficial twrp by pranaya 2005, the maintainer of Pixel Experience for santoni. MOD EDIT: Telegram link removed, please read the STICKY!
If you have encrypted device, your phone will ask for password. Most android 9 Roms don't ask for password. Most android 10 Roms (pixel experience, havoc) ask.
To fix this issue just go to twrp -> wipe-> format data.
It'll decrypt your device but remember to backup everything cause it'll wipe all data on your device.

Hi,
I finally decided to go with official lineage OS 16.1. Can you pls check me steps? Because, I am hearing lot about persist backups? fingerprint issue etc.
How to take persist backup?
Should I also take ROM backup using TWRP?
1- Unlock boot loader using official Mi software.
2- Flash recovery to TWRP
3- Wipe everything
4- Install ROM
5- Install Gapps

Yup...
0. Pick a day where you're absolutely sure you wont need to use your device for a whole day.
1. Unlock bootloader (I unlock my device unofficially cuz I hate waiting period. But I still recommend you to do it the official way).
2. Flash twrp (or any other custom recovery you like)
4. Back up everything via custom recovery. It may take up to 11 gb of storage so make sure you have more than enough free storage in your external sd card. If you dont have enough storage just backup everything except system partition which take a LOT of storage.
5.PRAY TO GOD
5.1. Use lucky charm(s)
5.2. - 5.9. Do everything you think may help with ur luck
6. Wipe Everything
7. Flash rom & gapps(if it isnt included in rom).
9. Reboot.
10. Enjoy... or not.
Note:
- it is what it is. Do it at your own risk.
- if ur fingerprint dont work and nothing happens even tho youve restored your persist back up. Go to thread about Los 16 fingerprind doesnt work created by me, there I gave link to a solution that works for my device.
- If 30-60 minute passes n ur phone hasnt boot then your phone maybe stuck in a bootloop. Go to twrp and reflash or try another rom. For me it usually takes less than 10 minutes to boot.
- if ur phone suddenly dies n you cant boot, fastboot or go to recovery. First, calm down. Take the back of the phone off carefully (you dont want to accidentally tore the fingerprint cable off). Try disconnect your battery from the phone n reconnect it. Then try go to fastboot or recovery.
- if reconnecting the battery dont work use edl mode (just search for edl mode redmi 4x for a guide).
- If edl mode dont work go to phone service. If they cant fix it just buy a new phone.

which havoc os version you are using on redmi 4 ?
I Am facing lot of problems with custom Rom such as usb not connecting to pc,middle touch not functioning , calls not working . I've done factory reset my device and everything working fine except phone not connecting to pc.
I don't know how i am possibly going to unlock bootloader it it's not going to connect pc.
i've updated pc driver and work through all solution, i think the problem is with miui stock rom 11 update as the same issue is posted on other threads.

I'm afraid I will also need to switch to a Custom ROM sooner or later, although my experience with santoni Custom ROMs was not too good. There was always something broken - be it Deep Sleep, GPS fix or fingerprint sensor.
At the moment I am trying to decide between
Resurrection Remix 8.6.x (Android 10)
Havoc OS 3.8 (Android 10)
AICP 15.0 (Android 10) - although an older version ~1 yr ago did not work too well
LineageOS 16.0 (Android 9)
and don't know what to choose. Stability and battery runtime are most important, I also need some basic customization, but no senseless bulls**t like animated unicorns running over the screen or things like that.
Which of the beforementioned work(s) well?

If someone still reads this...
I've tried RR and Havoc. I liked both and did not find any major bugs during my short tests, but the fact that full device encryption did not work is a big no-go.
Now I'm on LineageOS 16.0 official (with older Android 9) and despite the fact that there could be some more features and customization possibilities I am very satisfied with stability and performance.

I am using Samsung m31, Exynos 9611, this phone is Project Treble supported. Does anyone tried GSI?
As it is running on exynos any chance?

Yes, it runs. I am currently using Corvus OS on M31s.
Install TWRP as mentioned for your device and then follow this guide
How to flash a Generic System Image (GSI) on Project Treble supported devices
So your device supports Project Treble, what does that mean for you? It means you can flash a Generic System Image such as LineageOS or Resurrection Remix! Enjoy AOSP-based custom ROMs! Here's a guide on how to install these ROMs.

Can you explain how you installed corvus os on m31s?

Thanks in advance

Installed TWRP as mentioned in the forum.
Followed the steps for TWRP way of installing GSI in the link of my precious posts in this thread. Normally, boot into the GSI. That's it.
PS - Only Corvus OS allows SafetynetBypass. I have tried it on phhussons GSI and haven't been able to pass safetynet. Even dabbled with magisk hide prop config. Wasn't able to achieve anything.

Also, no GSI provides stable experience for long term as the stock with root. I am now running stock on my M31s as I need a working phone for use.

Ok, do we have any bugs with corvus os?

Yeah, you might encounter some unstability. But overall experience is really good. The phone is responsive most of the time. You could try if you want to see what it is. I haven't gone back to Corvus, ever since Android 12 update came, so maybe the new firmware might have added some fixes.

Yeah, I'm fascinated by the responsiveness of the corvus os. And this new android stock update is eating up more RAM. And I feel one UI 4.1 is not good as 3.1.
I'm thinking of weather to switch to gsi or not.
For long usability, what do you think will be the better option?
Switch to GSI or reset the existing stock rom user data?

Have you root

Have you rooted your phone? If you have, give the GSI a try. If not, try following ONE UI Optimization guide on xda itself. Then, decide, whether you want it or not. I use slightly debloated ONE UI 4 rooted and with certain floating feature tweaks and build.prop tweaks as well. It has given me good mileage, but not as much as the Redmi Note 5 Pro, when I installed Superior OS A12 on it. But it will be definitely better than factory.

You will definitely need a second phone if you want to try GSI

No, I haven't rooted me phone. I'll try one ui optimization .
Thank you for your suggestion

You could always try another GSI. https://github.com/phhusson/treble_experimentations/wiki/Generic-System-Image-(GSI)-list

Oh, I don't have second phone. I think it is better to stay on stock rom.

Thank you very much

Are volte and calls working fine?

Don't expect VoLTE on exynos on any GSI. Calls work OK.

LineageOS 20 Official available?

Hi.
LineageOS 20 is now officially released, but I can't find it for Sony Xperia XZ1c.
Does anyone know where it can be downloaded?
Thanks

There isn't official Los 20 for the XZ1c, but you have the unofficial version by derfelot. It works the same as the official versions for other devices, the only differences being the lack of OTA updates and the time between updates varies. I think we're getting an update to the Los20 rom soon, since I see commits submitted in github.

Hi,
I've installed the previous unofficial version on my XZ1c, and am looking forward to the mentionned unofficial LOS20 update before I install it (I didn't see it was already available at the time I installed 19 in december). I have a question, not too silly I hope :
I've read on LineageOS website that if some developers have a running and reliable LOS version developed for a device that is not yet officially supported, they can submit their version so that then the version becomes "official" and one can get it from LOS website. Is it planned with this unofficial LOS version ? why / why not ?
Thanks

I think It's not official because the devs don't want to involve/don't have the time to become official maintainers, instead releasing updates less frequently. Basically It's a responsibility. That's what I think and personally I'm fine with the unofficial builds, these devs do a lot already.
So in theory, If someone has the skills/time to maintain this device officially, It could become one without an issue.

Let me ask another question (since this is new post):
Which of available ROMs suits You all best and why?
I Was on Havoc 4, then 5, Lineage 17, now I'm back to Havoc 3.11 but this one gets random freezes and battery heats up. Only issue I have with new releases is lack of Android Auto support.

Hi, I don't have an answer to your question since so far I've tested only lineage 19. But I'd like to ask you why you chose to go back to Havoc 3.11 even though it heats and freezes ? (Why not a more recent ?)
And what are the differences between Havoc and LOS in everyday use, what did you personnally notice / prefer ?

Ok, indeed it would add more work/responsibility to the developpers.

Hi,
I wanted to try and test Android Auto mostly to be honest.
As per differences - Havoc gives You way more options to customize whole phone (appearance), have more features (gestures, status bar, dock etc., you might even forget half of the settings after finishing configuring it), Lineage on the other hand I believe consumes less battery, appears to be quicker, is neat.
But I've tried either Havoc and Lineage on Android 12 and both works smooth. Testing Lineage 20 currently and can't say any bad word. But I'm kind of lucky with custom ROMs, never had any major issues, all worked fine always
